| NOTE: To use any of these cranks in a 351W block with the stock Windsor size mains you must use the appropriate bearing spacers. The smaller diameter of the Cleveland size main journal offers many performance advantages while still being extremely strong. The smaller main journals result in a lighter crankshaft, reduced bearing speed, reduced friction, better oiling and other advantages. | ||||||
